The obstacle was made up of two swinging pegboards with seven holes in each pegboard, and several pegs which was placed into them (three on the first pegboard and one on the second pegboard).
Competitors have to hold on to a peg and place it to the holes, while trying to generate enough swing and momentum to traverse one peg to the other pegboard. After that, competitors have to generate enough swing and momentum to make a dismount from the second pegboard to the landing platform. Among the 19 competitors who attempted it, 10 of them could complete the obstacle.
The Swinging Peg Board was attempted early during Celebrity Ninja Warrior: Red Nose Day, when Stephen Amell gave a preview on this obstacle after completing the Salmon Ladder. Although he failed to complete it, his performance at that time was awarded the "M&M's Run of the Night", and won $35,000 for charity by completing seven obstacles.
